When it is necessary to tamp other positions of the conical barrel 51, the plug rod 44 is pulled out and the turntable 41 is rotated. The turntable 41 rotates to rotate the conical barrel 51 to other positions. After the position is rotated, the turntable 41 is fixed by the plug rod 44, and the compaction component 3 is used to tamp the concrete. When one layer is completed, the compaction component 3 is raised by the lifting component 2, and new concrete is added. This process is repeated.
